When an 8.2-magnitude earthquake struck off the coast of Chignik, Alaska, on July 29, geophysicist Geoffrey Abers did the logical – if not simple – thing.
He raced to Alaska with a group of collabora...
Seismologists monitor Ridgecrest quake aftershocks using novel fiber optic network（图）
Seismologistsr Ridgecrest quake aftershocks novel fiber optic network
2019/10/22
Seismologists at Caltech are using fiber optic cables to monitor and record aftershocks from the 2019 Ridgecrest earthquake in greater detail than previously possible. Thousands of tiny aftershocks ar...
Study Finds Earthquakes Can Trigger Near-Instantaneous Aftershocks on Different Faults
Earthquakes Trigger Near Aftershocks Different Faults
2016/9/29
According to a new study by scientists at Scripps Institution of Oceanography at the University of California San Diego, a large earthquake on one fault can trigger large aftershocks on separate fault...
Estimation of seismic moments from local magnitudes and coda durations for the Cairo earthquake aftershocks recorded at Kottamyia (KEG) Broadband station
aftershocks seismic moment scaling
2015/9/17
The spectral analysis of fifty-five KEG VBB records from the October 12, 1992 Cairo earthquake source region
was performed to obtain the seismic moment. We obtained this parameter in turn to develop ...
The oscillatory behaviour of the aftershocks rate of the 2001 Bhuj earthquake, India: observation and interpretation
aftershocks Bhuj earthquake Omori'sLaw GBA array Lg magnitude
2015/9/14
A damaging earthquake of Mw 7.7, which struck the Bhuj region of India on January 26, 2001, was followed by a large number of aftershocks. The aftershock data available at Gauribidanur Seismic Array S...
A rate-state model for aftershocks triggered by dislocation on a rectangular fault: a review and new insights
aftershocks earthquake triggering fault parameters rate-and-state Omori law
2015/9/8
We compute the static displacement, stress, strain and the Coulomb failure stress produced in
an elastic medium by a finite size rectangular fault after its dislocation with uniform stress drop
but ...
Analysis of the spatial distribution between successive earthquakes in aftershocks series
Aftershocks Earthquake catalogs Spatial distribution Scaling
2015/8/18
The earthquake spatial distribution is being studied, using catalogs for different recent aftershock series. The quality of the available data, taking into account the completeness of the magnitude, i...
Aftershocks in Modern Perspectives: Complex Earthquake Network, Aging, and Non-Markovianity
Aftershocks Modern Perspectives Complex Earthquake Network Aging Non-Markovianity
2012/2/24
The phenomenon of aftershocks is studied in view of science of complexity. In particular, three different concepts are examined: (i) the complex-network representation of seismicity, (ii) the event-ev...
Triggering of Aftershocks of the Japan 2011 Earthquake by Earth Tides
Japan 2011 earthquake, Aftershock Triggering, Earth tides
2011/9/1
The aftershock sequence of the devastating Japan earthquake of March 2011 is analyzed for the presence of periodicities at the Earth tide periods. We use spectral analysis as well as a time-domain met...

2009/12/31
The time dynamics of the aftershock sequence of the Al-Hoceima (Morocco) earthquake of 24 February 2004 has been investigated. The sequence of the occurrence times of the events with threshold magnitu...
We invoke a metric to quantify the correlation between any two earthquakes. This provides a simple and straightforward alternative to using space-time windows to detect aftershock sequences and obviat...
Loading rates in California inferred from aftershocks

2009/10/30
We estimate the loading rate in southern California and the change in stress induced by a transient slip event across the San Andreas fault (SAF) system in central California, using a model of static ...
Modeling afterslip and aftershocks following the 1992 Landers earthquake
Modeling after slip aftershocks following Landers earthquake
2014/4/15
One way to probe the rheology of the lithosphere and fault zones is to analyze the temporal evolution of deformation following a large earthquake. In such a case, the lithosphere responds to a known s...
